Nodular Skin Disease is where the horse develops raised nodules on the withers, back, neck, chest or abdomen.
Symptoms
Nodules appear and they are rounded, firm, non-irritating, painless, 0.5 - 5 cms (0.2 - 2 inches) in diameter and they can vary in number from 1 to several hundreds. Hair loss doesn't usually occur and the nodules may remain for months or even years. Nodular Skin Disease is usually confirmed by a skin biopsy carried out by your vet.
Cause
The cause is unknown, but the nodules usually develop in spring or summer so they could be a reaction to insect bites.
Treatment
Sometimes the nodules disappear without treatment, but if not corticosteroids may be effective or surgical excision may be necessary.
